METALLIC SHINGLE SPECIFICATION forming part of Letters Patent No. 356,161, dated January 18, 1887.

Application filed August 2, 1886.

To all whom, it may concern:

Be it known that I, ARTHUR RIOKETSON, a citizen of the United States, residing at New Bedford, in the county of Bristol and State of 'Massachusetts, have invented a new and usespurs on'one or both sides, formed by cutting through the metal shingle on two sides of a triangular space and bending the cut portion to a right angle with the surface for the purpose of holding the shingle in place.

In the accompanying drawings, Figure 1 is aplan viewof my invention. Fig. 2 is aviev. in cross-section through the line 00 m. Fig. 3 is a side view of Fig. 1.

' In Fig. 1 the spurs or projections are shown formed on one side of the shingle only; The metal is out through around the openings 9 on the sides 0 and d, and is then bent downward to a right angle with the surface of theshingle a. This operation forms the spurs f, as shown in Figs. 2 and 3. The spursf are thus formed in order that the top e of the shingle may be 0 easily pushed under the shingles of the roof at any desired point. 7

The device is applied by forcing the upper end, 6, of the shingle a under the shingles and over the leaky spot, and then pressing it down, which forces the spur-sf into the woodof the shingles contiguous thereto and thus holds the device firmly in place.

Instead of two spurs formed on the device there may be additional spurs formed, as h, Fig. 1.

I am aware that metallic shingles have been formed with ribbed projections or strengthening-beads, and with slots and tongues for connecting the adjacent shingles with watertight 'joints; but this I do not claim.

That I claim as my invention is A metallic shingle having triangular spurs formed thereon by cutting through the metal of the shingle on two sides of a triangular space and bending the cut portion to a right angle with the surface of the same, substantially as shown and described.

ATRHUR RIOKETSON.
